GLAZED STRUCTURE.

SPECIFICATION forming part of Letters Patent No. 595,805, dated December21, 1897. Application filed March 12, 1897. Serial No. 627,165. (Nomodel.)

To all whom it may concern:

Be it known that I, EDGAR W. CUNNING- HAM, a citizen of the UnitedStates, residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements in GlazedStructures, which improvements are fully set forth in the followingspecification and ac companying drawings, and in the latter Figure 1 isa perspective view of a glazed structure embodying my said improvements.Fig. 2 is a transverse section of same, the section being taken on theline a; 00 of Fig. 3. Fig. 3 is a detail plan view showing bindingdevice interposed between overlapping panels, as in Fig. 2, and adjacentdisjoined tubular cushions made use of, one panel being removed.

Similar reference-numerals indicate like parts throughout the severalviews.

This invention relates to improvements in glazed structures, the samebeing used for roofing purposes and for the sides of greenhouses,conservatories, and the like. Its object is to provide a structure ofthe character designated which shall be durable, simple, and inexpensiveas regards construction and which shall possess advantages especially inthe way of increased efficiency in operation over prior structures oflike character.

The invention consists in the novel forina-' tion of certain of theparts, in a novel disposition of the various parts, in certaincombinations thereof, and in certain details of construction, all ofwhich will be hereinafter specifically referred to,and clearly definedin the claims.

Having reference to the accompanying drawings, 1 denotes aglazing-support, ordinarily of iron, steel, or wood. This support is ofany suitable length and is provided with upwardly-curved wings 2, intothe concavity of each of which I place a disjoined tubular cushion 4, ofthin elastic sheet metal adapted to yield under pressure. I

5 denotes the glass panels, each resting along its edge upon one of thecushions 4, and in some instances overlapping one upon the other, asshown in Fig. 2.

The support 1 is provided with a central upright web 6, carrying rigidvertical bolts 7,

each threaded at its upper end to receive a nut 8. sembling in crosssection an inverted U, straddles longitudinally the vertical web 6, andeach of its depending sides is folded or bent upon itself to form ridges10, between the opposing walls of which is inserted one end of acontinuous binding-strip of flexible, spring, or yielding thin sheetmetal 11, preferably brass, the said walls of the ridge 10 beingsqueezed snugly together, thereby serving to prevent displacement of thestrip 11. The depending sides of the cap 9 each terminate in a flaringportion 12, which extends over and thereby serves to protect from theelements the strip 11, the latter, when the parts are in place, restingalong its lower .edge upon the panel 5.

The cap 9 is provided with openings arranged at suitable intervals alongits uppermost portion, through each of which openings projects one ofthe vertical bolts 7, which .carries on its threaded end a nut 8.

Intermediate of the overlapping edges of .the panels 5, as shown in Fig.2, I dispose a weather or binding device of yielding sheet metal, asbrass, said device consisting of a slightly-curved body portion 13, bentdown ward at one edge to form a straight wall portion 14, adapted toabut against the adjacent edge of the underlapping panel 5, said wallportion 14 being bent outward at a suitable angle to the portion 14 andterminating in a portion 14, thereby forminga condensationgutter, thelatter communicating at its respective ends with the disjoined tubularcushions 4, to admit of which said cushions are each cut away, as at 15.With this construction water of condensation finds its way to the gutterformed by the portions 14 and 14 of the binding device,'from whence itis discharged into the cushion 4 and after passing along the latter, orthe wings 3, may be conveyed to any desired point in any common andwell-known manner.

Having placed the disjoined tubular cushions 4 in the wings 2, thepanels 5upon the cushions 4, the cap 9 over the web 6, with the bolts 7projecting through the openings therein, and the nuts 8 on the bolts 7,upon turning the nuts 8 homeward the result will be to urge the cap 9downward, thereby forcing A sheet-metal continuous cap 9, re-

IOG

the strip 11 against the panels5, the strip, being of yielding material,finding its way into any depressions that may exist in the panels 5, theflarin g portion 12 coming in contact with the latter, whereupon theoverlapping edges of the panels 5 are primarily urged together upon thecurved portion 13 of the binding device and secondarily urged downwardupon the cushions 4, with the 'result tween the overlapping edges ofsaid panels,

that the latter tend to close more or less and an upwardly anddownwardly yielding disposition of the panels is secured.

It will be observed that in my improved structure evil effects resultingfrom contraction and expansion of any of the parts are largely, if notentirely, obviated, water-tight junctions are secured at all points, andan easy-yielding disposition of the panels is attained.

From the foregoing description of my improved glazed structure it willbe seen that the same is simple and inexpensive in construction and isespecially well adapted for the purpose for which it is designed; and itwill also be obvious that the same is susceptible of some modificationwithout material departure from its principles and spirit, and

for this reason I do not wish'to be understood as limiting myself to theprecise form and arrangement of the parts as herein set forth.

Having fully described my invention, what metal, and comprising a curvedportion, a a straight portion arranged at an angle thereto, and aportion 14: arranged at an angle to the straight portion, the saidcurved portion being interposed between the overlapping edges of saidpanels, as herein shown and described.

2. In a glazed structure, the combination of overlapping panels, abinding device, comprising a curved portion, a straight portion arrangedat an angle thereto, and a portion 14:, arranged at an angle to thestraight portion, said curved portion being interposed bethereby forminga gutter, and suitably-disposed, disjoined, tubular cushions, supportingsaid panels, the gutter named being arranged to communicate with saidcushions,

, as herein shown and described.

3. In a glazed structure, in combination with a glazing-support,provided with a vertical web, s uitabl y-disposed panels, a continuouscap, straddling said web, yielding sheetmetal binding-strips, onesecured along its upper edge to each of the depending sides of said cap,and arranged so that its lower edge portion may be pressed against thepanel, through downward movement of said 'cap andmeansforurgingsaidcapdownward,asherein shown and described. V

4. In a glazed structure, in combination with a glazing-support,suitably-disposed panels, a cap, straddling said support, and

' having its depending sides each folded upon itself to form a rib, ayielding binding-strip, held at its upper edge between the opposingwalls of said rib, and in contact, at its lower edge, with the panelsaforenamed, and means for urging thecap'downward, as herein shown 1 anddescribed.
